NADO 500, 750, 1000 v2

Character

Storage tanks NADO are produced with a flange with spacing of screws 210 mm for assembly with a heating flange TPK. The tank contains an exchanger with heating surface 1.5 m2 for connection to another heating system (for example SOLAR). The tank contains an inner enamelled vessel of 140 liters volume, according to dimension of the storage tank. Placement and quantity of sockets can be changed in dependence on an order. In the standard design the flange is closed. Storage tanks are delivered without insulation. The insulation is available on request.

NADO 300, 500, 750, 1000 v6

Character

NADO v6 accumulation tanks are produced with two G 6/4" funnels to assemble a screw-in heating unit TJ with an extended cooling unit of 2×6 kW maximum power output. The tank contains a tubular steel exchanger of 1.6, 2.2 or 3.3 m2 surface to connect an additional heating system (e.g. SOLAR). The tubular steel exchanger placed in lower part of the tank cannot be used for flow heating of hot water. The tank contains a submerged stainless steel exchanger for preparation of hot water of 20, 25, 35 or 45 litre capacity, depending on the size of accumulation tank. Upon customer's request, the distribution of funnels and their quantity can be modified. Accumulation tanks are supplied without insulation. The insulation is available on request.

Character

NADO accumulation tanks are produced with two G 6/4" funnels (it does not apply to the 500 litre capacity) to assemble a screw-in heating unit TJ with an extended cooling unit of 2×6 kW maximum power output. The tank contains an exchanger of 2.5 or 3.3 m2 surface to connect an additional heating system (e.g. SOLAR). The tubular steel exchanger placed in lower part of the tank cannot be used for flow heating of hot water. The tank contains an inner enamelled accumulator of 200 litre capacity. Upon customer's request, the distribution of funnels and their quantity can be modified. Accumulation tanks are supplied without insulation. The insulation is available on request. The NADO 500/200 v7 accumulation tank cannot be equipped with heating with electrical elements.
